D2, an embedded IP communications software firm that has offered Linux-ready VoIP stacks for WiFi-enabled smartphones, says that it will privately demonstrate the reference design this week at ITExpo East 2009 in Miami. The design is said to be a turnkey solution for handsets and "similar portable devices" that combine any two of the following radios: WiMAX, WiFi, and cellular.
The reference design is built on an undisclosed OMAP platform from Texas Instruments (TI), which is probably the handset-oriented OMAP34xx system-on-chip (SoC), or possibly one of the general-purpose OMAP35xx SoCs. Both OMAP platforms incorporate ARM's superscalar Cortex-A8 processors.
The OMAP3 chips are available with or without a built-in TI DSP (digital signal processor). We're guessing the design eschews a hardware DSP, since it is said to include D2's softDSP VoIP engine. Also included is D2's mCUE mobile client stack (diagram below), along with codecs, error correction, jitter buffer, and a host of other VoIP technology, says the company. The design reportedly supports standard IMS-SIP, along with an alphabet soup of more proprietary VoIP technologies.

mCUE features are said to include:Presence-based and push-to-x controls
Cellular and VoIP calls (though cellular likely not used in this design)
PBX feature activation
IM, email, and SMS
Interoperability with communications services like IP PBXs and UC systems
Interoperability with commercial "VoIM" services like Google Talk, Yahoo!, MSN, and AIM
Customizable UI elements, including contacts address book with presence (see image at top) and IM chatStated Doug Makishima, VP of marketing and sales at D2 Technologies, "The industry is pouring tremendous resources into the creation and delivery of a WiMAX infrastructure, and manufacturers will need a fast and cost-effective way to develop mobile devices that take advantage of the greater bandwidth, range, and other benefits of this technology."
Availability
D2 Technologies will privately demonstrate the Linux reference design at ITExpo East 2009 in Miami, Florida, from Feb. 2-4. The Google Android and Windows CE/Mobile versions are due in the second quarter. More on the underlying mCUE software may be found here .
